Design inspired by those cool ass skull autococker parts. More matching parts coming soon. Skull originated as open source file on tinkercad with commercial use license, but link appears to no longer exist. I heavily modified it from its original form. Added to pops bonnet file released by Planet Eclipse.
Use snug fitting allen wrenches to ream/bore holes for easier function (warning this voids shapeways warranty).
